I would also like to see a feature that disabled images larger than your average banner. Those car images and whatnot bother me. Why can't they just be linked to instead of displayed entirely?

Signatures are meant to inform or entertain. I do not mean to make a specific example of you, Tublear, but your signature epitomizes it to me: the image is included for no real reason other than to "look cool." It does not state anything, provide personal information, or entertain. It is just there. In that situation, I think it should be just linked to instead.

This isn't just you, though. There are many other signatures which fall into this trap.
